mac下修改mysql的默認字符集為utf8

mac下修改mysql的默認字符集為utf8

 

1,檢查默認安裝的mysql的字符集

 

mysql> show variables like '%char%';
+--------------------------+--------------------------------------------------------+
| Variable_name            | Value                                                  |
+--------------------------+--------------------------------------------------------+
| character_set_client     | utf8                                                   |
| character_set_connection | utf8                                                   |
| character_set_database   | latin1                                                 |
| character_set_filesystem | binary                                                 |
| character_set_results    | utf8                                                   |
| character_set_server     | latin1                                                 |
| character_set_system     | utf8                                                   |
| character_sets_dir       | /usr/local/mysql-5.5.23-osx10.6-x86_64/share/charsets/ |
+--------------------------+--------------------------------------------------------+
8 rows in set (0.00 sec)

 

character_set_database和character_set_server依然是latin1的字符集,也就是說mysql後續創建的表都是latin1字符集的,不是utf8,會造成一些麻煩。所以有必要修改my.cnf,在修改my.cnf之前一定要關閉mysql進程,不然會遇到mysql的sock不能連接的問題。

2,關閉mysqld後臺進程

 

系統偏好設置裡面控制mysqld,避免瞭去找mysqld安裝位置的麻煩。

 

 

點擊 Stop MySQL Server

 


 

3,修改mysql配置文件/etc/my.cnf

 

sudo cp /usr/local/mysql/support-files/my-medium.cnf /etc/my.cnf

sudo vi /etc/my.cnf

[client]部分加入:
default-character-set=utf8
[mysqld]部分加入:
character-set-server=utf8

 

退出並保存:

 

按住ctrl鍵再連按兩次z鍵

 

 修改完畢之後再啟動mysql

 

4,檢查結果:

 

mysql> show variables like '%char%';
+--------------------------+--------------------------------------------------------+
| Variable_name            | Value                                                  |
+--------------------------+--------------------------------------------------------+
| character_set_client     | utf8                                                   |
| character_set_connection | utf8                                                   |
| character_set_database   | utf8                                                   |
| character_set_filesystem | binary                                                 |
| character_set_results    | utf8                                                   |
| character_set_server     | utf8                                                   |
| character_set_system     | utf8                                                   |
| character_sets_dir       | /usr/local/mysql-5.5.23-osx10.6-x86_64/share/charsets/ |
